POLISHINGVDEVICE Filed June 24, 1935 I8 77/ar/7m775a 6000% ATTO R N EYPatented June 23, 1936 UNITED STATES PATENT OFFICE POLISHING DEVICEThurman E. Babcock, Lansing, Mich. Application June 24. 1935, Serial No.28,205 2 Claims. (01. 15-210) The invention relates to a polisher andmore especially to a rail or pole polishing device.

The primary object of the invention is the provision of a device of thischaracter, wherein a polishing cloth or other medium can be embracedabout poles or pipes, such as brass rails in buildings or the like, anda wide range of stroke obtainable for the polishing operation, thuseliminating the necessity of a person, when polishing, climbing a ladderfor the polishing operation overhead, as the device is susceptible oflong reach.

Another object of the invention is the provision of a device of thischaracter, wherein the construction thereof is novel in form, so that 0it can be readily mounted about a piece of work, such as a nickel orbrass rail or pole, and the latter can be polished with dispatch andthereby eliminating the hand application of a polishing cloth as isordinarily required.

A further object of the invention is the provision of a device of thischaracter which is simple in construction, thoroughly reliable andeffective in its purposes, readily and easily applied to 2 and removedfrom a piece of work, manually operable, strong, durable, andinexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction,

3 combination and arrangement of parts as will be hereinafter more fullydescribed in detail, illustrated, in the accompanying drawing, whichdiscloses the preferred embodiment of the invention, and pointed out inthe claims hereunto ap- D pended.

In the accompanying drawing:

Figure 1 is a fragmentary side elevation of a pole, showing the deviceconstructed in accordance with the invention applied for polishingthereof, the device being partly broken away.

Figure 2 is an elevation of the device, showing by full lines the closedposition and by dotted lines the open position.

Figure 3 is an end elevation.

Figure 4 is an elevation looking toward the inner face of one of thejaws of the device.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, there is illustrated a portion of abrass or nickel pole which is designated at A and to the same is appliedthe polishing device embodying the present invention and hereinafterfully describe This polishing device comprises a split clamping memberforming opposed jaws 5 and 6, respectively, these, through the medium ofpintle eyes I and a pintle 8 engaged therein, being swingingly connectedtogether for opening and closing movements. These jaws 5 and 6 atdiametrically opposite sides are formed with'trunnions 9 projectedlaterally therefrom and loosely received in slots Ill formed in the armsll of a fork 12 which, medially thereof, is provided with a handlesocket extension l3, the fork being disposed at an angle to theextension l3, and into the latter is wedged the tapered end I4 of ahandle I5, the length of the latter being governed according to theheight of the pole A to be polished, therefore, it being understood thatsuch handle may be of any required length, as the occasion may require.

Surrounding the trunnions 9 are coiled expansion springs l6, theseplaying against the jaws 5 and 6 and also against the inner faces of thearms ll of the fork l2 and functioning to sustain the jaws 5 and 6closed.

Adapted to be disposed about circle the same is a polishing cloth I! andthis cloth is embraced by the jaws 5 and 6 which are opened manually, asis disclosed by dotted lines in Figure 2, and thereafter the springs I6,when the said jaws are released, will close the same about the cloth IT,as shown in Figurel of the drawing. On manipulation, through theinstrumentality of the handle l5 by hand, the device when reciprocatedwill have the said cloth l1 polish the pole A. By reason of the extentof the handle, the stroke of the device may have an extended range, sothat the pole A'can be reached at the extreme of its height.

When it is desired to remove the cloth H from about the pole A, the jaws5 and 6 are manually opened against the resistance of the springs l6 andthus such cloth becomes released.

Each jaw 5 and 6 has provided on its inner face the depressions l8,these provide gripping areas I9 therebetween so as to effect a firm andsecure hold upon the polishing cloth to avoid the slipping of the clothwith relation to the jaws 5 and 6 when the device is in operation.

What is claimed is:

1. A device of the character described comprising a clamp having hingedjaws, a fork having side arms spaced from each other a distance greaterthan the size of the clamp, lugs projecting laterally from the jaws ofthe clamp and loosely fitting the side arms of said fork, springscarried on the lugs and arranged between the side arms of the fork andthe jaws of said clamp the pole 8 to enand normally holding the jawsclosed, and a handle fitted with said fork.

2. A device of the character described comprising a clamp having hingedjaws, a fork having side arms spaced from each other a distance greaterthan the size of the clamp, lugs projecting laterally from the jaws ofthe clamp and loosely fitting the side arms of said fork, springscarried on the lugs and arranged between the side arms of the fork andthe jaws of said clamp and normally holding the jaws closed, and ahandie fitted with said fork, the side arms of the fork being slottedfor permitting the displacement of the lugs therein on the opening ofsaid jaws against the resistance of the springs.
